Note: As with all such firmware upgrade, there is a risk of bricking your iFi product if something went wrong during the upgrade. If your iFi product is bricked, you need to send it back to the dealer/distributor for repair.

Hence we do not recommend the user to upgrade or downgrade the firmware just for fun. Only do the upgrade or downgrade when necessary.
